The study's purpose was to obtain improved "deplasticizing" of epoxy sections for immunoelectron microscopy. Epoxy-embedded renal swine tissue with immune complex deposits was used. Ultrathin sections were mounted on uncoated grids or on carbon-stabilized formvar grids. The sections were exposed...

The purpose of this investigation was to develop a method that could be used to estimate how damaging sodium ethoxide is to different antigens with respect to immunolabeling when epoxy sections are deplasticized. If we obtain weak labeling for an...
